This metadata record describes a series of data sets of climate and land-use/land-cover features (provided in parquet file format) linked to NHDPlus Version 2.1’s (NHDPlusV2) stream segments, their associated catchments and their upstream watersheds within selected regions in the conterminous United States. All data can be linked to NHDPlusV2 using the COMID field in these tables and the...
Quaternary ammonium compounds in wastewater treatment effluents from 2020 to 2021 Quaternary ammonium compounds in wastewater treatment effluents from 2020 to 2021
Quaternary ammonium compounds (QAC) are used in many commercial and household disinfection products. A method was developed to measure QAC occurrence in water discharged from three wastewater treatment plants during 2020 and 2021. Water samples (20 mL) were processed via solid phase extraction using weak cation exchange (WCX) cartridges (3 cc, 60 mg) and analyzed via liquid...
Multilevel Monitoring System (MLMS) datasets for wells in the U.S. Geological Survey - Idaho National Laboratory groundwater monitoring network Multilevel Monitoring System (MLMS) datasets for wells in the U.S. Geological Survey - Idaho National Laboratory groundwater monitoring network
A collection of analysis-ready Multilevel Monitoring System (MLMS) datasets for wells in the U.S. Geological Survey (USGS) aquifer-monitoring network, Idaho National Laboratory (INL), Idaho. Administered by the USGS INL Project Office in cooperation with the U.S. Department of Energy.
Weekly Changes of Exotic Annual Grasses (EAG) abundance in the Sagebrush Biome, USA, 2024 Weekly Changes of Exotic Annual Grasses (EAG) abundance in the Sagebrush Biome, USA, 2024
These datasets provide weekly differences of early estimates of 2024 fractional cover for exotic annual grass (EAG) that were released from April to late June. The EAG estimates were publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contained five fractional cover maps along with their corresponding confidence maps for: 1) a...
Hydrogeologic framework top-surface altitude rasters for the Virginia Eastern Shore Hydrogeologic framework top-surface altitude rasters for the Virginia Eastern Shore
In support of a groundwater-flow model of the Virginia Eastern Shore, altitudes were determined for the tops of hydrogeologic surfaces, including incised paleochannel surfaces, that compose the framework within the model area. Rasters were generated from the altitude data for the tops of the surficial aquifer, upper confining unit, upper aquifer, middle confining unit, middle aquifer...
Estuarine Shoreline, Upland Boundary, and Marsh Habitat Change Analyses for the Point Aux Chenes and Grand Bay Estuary Systems, Mississippi and Alabama Estuarine Shoreline, Upland Boundary, and Marsh Habitat Change Analyses for the Point Aux Chenes and Grand Bay Estuary Systems, Mississippi and Alabama
Coastal marshes across the Northern Gulf of Mexico are critical ecosystems, providing wildlife habitat, nursery for many species of fish, a carbon sink, and protection of communities from storm surge, but are vulnerable to coastal hazards, such as wave attack, sea level rise, and subsidence. While many marshes accrete vertically to compensate for rising sea level, marsh loss can occur...
Data on the behavior of grass carp, silver carp, and bighead carp during laboratory exposures to the amino acids L-alanine, L-arginine, L-aspartic acid, and L-glutamic acid Data on the behavior of grass carp, silver carp, and bighead carp during laboratory exposures to the amino acids L-alanine, L-arginine, L-aspartic acid, and L-glutamic acid
These data pertain to behavior trials conducted on three different species of invasive carp in a laboratory setting between the dates of 29 April 2021 to 14 December 2021. The three species tested were grass carp (Ctenopharyngodon Idella), bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix). The amino acids L-alanine, L-arginine, L-aspartic acid, and L‑glutamic acid...
U-Pb zircon geochronology and whole rock geochemistry data for Auminzatau and Kuldjuktau mountains, Kyzylkum desert, Uzbekistan U-Pb zircon geochronology and whole rock geochemistry data for Auminzatau and Kuldjuktau mountains, Kyzylkum desert, Uzbekistan
These U-Pb zircon geochronology and whole rock geochemistry data were collected as part of a bilateral campaign of the U.S. Geological Survey (USGS) with the Uzbekistan Ministry of Mining, Industry, and Geology (MinGeology; formerly GOSCOMGeology) to support a new quantitative/qualitative mineral resource assessment for tungsten, gold, rare-earth elements, graphite, and uranium in the...
Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020 Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020
This dataset contains Sanger ITS sequences from biocrust lichen taxa collected at Horse Heaven Hills in Washington, USA. It also includes metagenomic biocrust lichen data from 20 plots at Horse Heaven Hills in Washington, USA. These data were collected by Bruce McCune and Heather Root in 2019-2020 and sequenced for ITS using bulk sequencing in the PacBio system at Brigham Young...
Data describing a predatory fish invasion on a riverine food web Data describing a predatory fish invasion on a riverine food web
Catfishes are opportunistic feeders that are among the world's worst invasive species. Flathead catfish *Pylodictus olivaris* -- a large predatory catfish -- were first detected in the Susquehanna River, Pennsylvania, USA in 2002. Since then, they established a viable and rapidly growing population that is expanding its range throughout the river system. Although the predatory effects of...
Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits
Pegmatites are a major host of global lithium, cesium, and rubidium resources. However, the existing grade and tonnage dataset for lithium pegmatites that was published in 1992 does not represent the current industry parameters used to delineate resources. There are no existing grade and tonnage datasets for cesium and rubidium. We present grade and tonnage data for lithium, cesium, and...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...
